2008 Konstitutsiya, provisionally designated1973 SV4, is a carbonaceousasteroid from the outer region of theasteroid belt, approximately 50 kilometers in diameter. It was discovered on 27 September 1973, by Soviet astronomerLyudmila Chernykh at theCrimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[11] The asteroid was named for the1977 Soviet Constitution.[2]
Konstitutsiya orbits the Sun in theouter main-belt at a distance of 2.9–3.5 AU once every 5 years and 9 months (2,105 days). Its orbit has aneccentricity of 0.10 and aninclination of 21° with respect to theecliptic.[1]In September 1938, the asteroid was first identified as1938 SV atTurku Observatory, Finland, extending the body'sobservation arc by 35 years prior to its official discovery observation at Nauchnyj.[11]
Konstitutsiya is an assumedC-type asteroid.[5]
Two rotationallightcurves ofKonstitutsiya were obtained from photometric observations in 2011. Lightcurve analysis gave arotation period of 11.2692 and 11.279 hours with a low brightness variation of 0.08 and 0.06magnitude, respectively (U=3/3-).[9][10] A low brightness amplitude suggests that the body has a nearly spheroidal shape.
According to the surveys carried out by the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Konstitutsiya measures between 45.46 and 53.942 kilometers in diameter and its surface has analbedo between 0.0505 and 0.070.[3][4][6][7][8] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0580 and a diameter of 50.31 kilometers based on anabsolute magnitude of 10.2.[5]
Thisminor planet was named on the occasion of the adoption of the new1977 Soviet Constitution, also known asBrezhnev Constitution.[2] It was the third and last Soviet Constitution ever to be adopted. The officialnaming citation was published by theMinor Planet Center on 1 September 1978 (M.P.C. 4481).[12]
